setting raspberry pi 4
December 16, 2023, 13:10
Hello guys, I'm trying to set up a raspberry pi 4. My setup is headless. I don't set up a wireless lan connection.
When I connect the lan cable between my laptop and the raspberry pi I try to open ssh with putty, and it couldn't find the host
A cross cable is required for such a connection.
It is a cross cable, I already made a connection, but since then I couldn't do anymore, so I loaded a new os and tried again, it's not working
Hostname and co entered correctly?
Have you tried SSH via the console?
SSH also switched on in the imager?
Yes I tried pi@raspberrypi.local and raspberrypi.local at putty, both don't seem to work.ssh enabled at imager
Thank you for trying to help btw
Have you tried SSH via the console?
havent tired yet, how do i do this?
currently download a new OS, imager 1.8.3, rpi4, bookworm 64bit with desktop.
hostname: matanpi.local
username: pi
password:
no wireless LAN
SSH ON in the imager
should I add a ssh file in the SD card?
This will cause problems, as far as I know bookworm is not optimized for Pi 4.
No, but try an SSH connection via the console/terminal instead of PuTTY.
ok so i changed for bullesye OS 32 bit.
No 64bit
bullesye 64bit?
Yes
ok.
how i do ssh connection via terminal?
Windows=CMD
Mac= don't now
just type in cmd ssh pi@matanpi.local?
No Open CMD then ssh
C:\Users\mtnda>ssh
usage: ssh [-46AaCfGgKkMNnqsTtVvXxYy] [-B bind_interface]
[-b bind_address] [-c cipher_spec] [-D [bind_address:]port]
[-E log_file] [-e escape_char] [-F configfile] [-I pkcs11]
[-i identity_file] [-J [user@]host[:port]] [-L address]

[-Q query_option] [-R address] [-S ctl_path] [-W host:port]
[-w local_tun[:remote_tun]] destination [command]
C:\Users\mtnda>
thats what I see when I type ssh
ssh pi@matanpi
could not resolve hostname matanpi. no such host is known.
only green led at the rpi4. is it fine?
Only green LED on the Pi? No red one?
Hmm strange, maybe it would be better to connect the Pi to LAN instead of directly to the laptop. I don't know how it works with IP without DHCP. I haven't tried that yet.
ok so I have a PC connceted to LAN. I connected the rpi4 to LAN too.
now I guess I need to ssh via my PC
Btw, both leds are on now
cant ssh it
Did you just reconnect the cables or restart the Pi?
I restart the Pi and connected it with ethernet cable to the router
Can you look into the router, if so see if the Pi appears there.
No, sadly I cant connect to it because I dont remember the username and password, but I can look with Advanced IP Scanner
Cant find any product with raspberry as the manufacture
I don't know of any router that displays manufacture...
Unplug the Pi, see which IPs are left and then plug it back in. Then you can see which IP is added.
How did you just set it up and have already forgotten your name and password?
I was trying few days so set it up. and suddenly I typed in putty pi@matanpi.local and it works. went to sleep, saw the raspberrypi with only red led. and couldnt enter it via ssh again...
well, I see the Pi at the network with IP 192.168.1.172
when I try ssh 'IP'
-connect to host 'IP' port 22: Connection timed out
OH thats new:
The authenticity of host '192.168.1.172 (192.168.1.172)' can't be established.
ED25519 key fingerprint is SHA256:ea+RMquFXO8zRSU+TFjEgLt+5JUh6lkguPTl78pqRvA.
This key is not known by any other names
Are you sure you want to continue connecting (yes/no/[fingerprint])?
Yes
SSH always requires
ssh username@hostname
Or
ssh username@ip
well, I enterd the password and then it sayed - Connection closed by 192.168.1.172 port 22
How exactly did you establish the connection now?
i typed in the CMD 'ssh 192.168.1.172'
then it asked my yes no or finger print. I sayed yes
SSH always requires
ssh username@hostname
Or
ssh username@ip
well i tried it no
ssh pi@192.168.1.172
i entered the password and it says, permission denied please try again
Have you set the Pi as a user in the imager? You just said that you forgot your username and password...
what do you mean as a user?
yes i set username and password. with username being pi and password rotempi
btw when I try ssh pi@matanpi Its not working either
Try it with another user.
which user?
I tried login with the laptop. Not working as well ><
You can choose your username as well as the hostname.
OK I will BOOT again
Raspberry PI OS Legacy 64 bit,
hostname: pitry.local
username: matan
password: matanpi
Is it fine?
Yes
the Pi is on, both LEDs are on, same IP 192.168.1.172
i try ssh matan@192.168.1.172
ssh: connect to host 192.168.1.172 port 22: Connection timed out
How long has it been running? The system takes a few minutes to install.
around 5 minutes
ssh matan@pitry
?
ssh: Could not resolve hostname pitry: No such host is known.
well I reconnected the Pi to the network and now he ask again ye/no/fingerprint
and i'm in!
Thank you! I guess i need vnc now
VNC does not work with headless! VNC is for GUI installations.
why not? VNC is just connecting to the PI and visualizing the desktop
Headless = No Desktop!
But you can try PuTTY again.
But I installed rpi with desktop
At first they said headless... That's why I assumed that now...
Yes then vcn works, but no idea how to set it up now. I only work headless.
Yes by headless I meant not monitor, sorry 😛
Anyways, Much thank you sir !
I restart the Pi and now only red LED is on, what does it indicate?
That the Pi has nothing to do that would cause the green one to light up.
As long as it can be reached via ssh or vcn, it is irrelevant whether the green one is lit or not.
By the way, with Linux headless always means without GUI. So be careful when using this word.
